Benefits of technology

The present invention provides an ink jet recording apparatus that can adjust the viscosity of ink liquid by replenishment with a solvent from a solvent cartridge. The apparatus is designed to be a continuous type ink jet recording apparatus. The technical effect of the invention is to allow for efficient and precise ink jet recording using a continuous ink system that can easily adjust the viscosity of the ink liquid.

Problems solved by technology

However, in the methods in which a reserve tank is installed in an ink jet recording apparatus, filling the reserve tank with ink may cause contamination of the surroundings of the reserve tank.
This fact shows that although the method of JP 2011-500353 W is effective to confirm that the cartridge has become almost empty, it is virtually not possible to more accurately detect that the cartridge has actually become empty.

embodiment

[0041]Hereinbelow, a preferred embodiment of the present invention will be described with reference to the accompanying drawings.

[0042]Automatic Printing System and Ink Jet Printer:

[0043]FIG. 1 is a diagram illustrating the outline of an example of an automatic printing system which includes a cartridge type ink jet recording apparatus. The illustrated automatic printing system 1 includes an ink jet recording apparatus 2 of the embodiment, a workpiece detection sensor 4, a conveyance speed sensor 6, a display device 8, and the like.

[0044]The ink jet recording apparatus 2 is generally called “ink jet printer”. Therefore, the ink jet recording apparatus 2 will be described using the term “ink jet printer”. The ink jet printer 2 is a continuous type printer which continuously jets ink. The ink jet printer 2 of the embodiment is installed in a workpiece conveyance line 10 and used for printing characters or graphics on a workpiece W flowing on the workpiece conveyance line 10. The workp...

Abstract

An object is to directly detect the emptiness of a solvent cartridge being mounted. An emptiness detection unit body includes a light transmissive tube which constitutes part of internal piping of a printer body, a light emitter, and a light receiver. The light transmissive tube is composed of a transparent tube, typically, a glass tube or a fluororesin (PFA) tube. The light emitter and the light receiver are arranged to face the light transmissive tube. The light transmissive tube is filled with a solvent supplied from the solvent cartridge. On the other hand, the light transmissive tube is filled with gas when the solvent cartridge is empty. The emptiness of the solvent cartridge is detected by a change in the amount of light received by the light receiver associated with the change in the light transmissive tube.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present application claims foreign priority based on Japanese Patent Application No. 2014-006196, filed Jan. 16, 2014, the contents of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]1. Field of the Invention[0003]The present invention relates to a continuous type ink jet recording apparatus which adjusts the viscosity of an ink liquid using a solvent supplied from a solvent cartridge, and more specifically to an ink jet recording apparatus having a function of detecting the emptiness of the solvent cartridge.[0004]2. Description of Related Art[0005]An ink jet recording apparatus is used for printing characters or graphics on the surface of a workpiece (JP 2007-190724 A). The ink jet recording apparatus is generally called “ink jet printer”. The ink jet printer includes a head which is placed above a manufacturing line and a controller body which supplies ink to the head. The ink jet printer charges an ink l...
